Stellar Jet to Unveil Revolutionary Hydrogen Technologies

StellarJet, a trailblazer in the realm of hydrogen-powered aviation, is gearing up for an exciting showcase at the Paris Air Show in 2025. The company is set to present two cutting-edge innovations that promise to redefine the landscape of clean flight: a breakthrough Solid-State Hydrogen Storage Unit and an advanced Electric Ducted Fan (EDF).

Solid-State Hydrogen Storage Unit

The first innovation, a solid-state hydrogen fuel storage tank, represents a major leap forward in aviation technology. This unit achieves a remarkable hydrogen content of 23% wt and boasts a high energy density of 6.6 kWh/kg, making it significantly more efficient than conventional liquid hydrogen systems. Designed for versatility, the storage unit operates safely between temperatures of -60°C and +80°C and facilitates rapid refueling in under 30 minutes.

According to Alexey Popov, the CEO of Stellar Aircraft, "This storage solution marks a turning point in aviation. Previous limitations of hydrogen storage systems have hindered the potential of hydrogen-powered flight. Thanks to our collaboration with rocket science experts, we have developed a safe, scalable, and high-performance storage system."

One of the standout features of StellarJet's solid-state hydrogen storage technology is its ability to provide a customizable design that enhances safety. Unlike traditional liquid hydrogen systems with potential boil-off and explosion risks, this solid-state alternative utilizes advanced metal hydride technology, ensuring superior safety and performance. With its compact design, the solid-state system stores more usable energy per weight unit while being more cost-effective and easier to certify under aerospace regulations.

Beyond aviation, this innovative storage solution finds potential applications in various sectors, including industrial operations, aerospace, satellite, and even maritime usage.

Electric Ducted Fan (EDF) Propulsion

The second breakthrough is an Electric Ducted Fan (EDF) propulsion unit, which delivers an impressive 132 kW of power and 1700 N of thrust, while maintaining a lightweight of only 14.7 kg. The EDF features a duct diameter of 375 mm and comes with an integrated power controller, exemplifying the next stage in distributed electric thrust architecture specifically designed for StellarJet.

All core technologies, from initial design and engineering to machining and final assembly, are entirely developed and produced in-house at StellarJet's headquarters in Austin, Texas. This vertical integration ensures quality control and innovation throughout the development process.

StellarJet's unveiling at the Paris Air Show will pave the way for the highly anticipated flight debut of their hydrogen-powered StellarJet Demonstrator, scheduled for Summer 2025. As they continue to push the boundaries of technological advancement in aviation, StellarJet embodies a commitment to sustainability and emission-free travel.

In an era increasingly focused on reducing carbon footprints, StellarJet’s innovations could be pivotal in ushering in a new age of green aviation, potentially reshaping air travel as we know it.

For more insights about these breakthroughs and the future of hydrogen aviation, updates will be shared on StellarJet's official website leading up to the significant event in Paris.
